Problems solved by technology

[0003] The technical problem to be solved by the present invention: when 220kV large-section power cables are laid horizontally or vertically in waves, due to the large cross-section and heavy weight of the cables, the distance between the cable lengths between the two support frames is relatively large, so that the artificial bending of the cables is almost impossible. Impossible, the existing bending equipment cannot meet the requirements of arc length for serpentine or wave laying

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] The cable bending machine of this example includes two hoops and a protruding device; the protruding device is arranged between the two hoops; The corresponding cable contact surface; the tail end of the ejector rod is connected to the jack, and the ejector rod is the ejector rod of the jack. A rubber pad is provided on the contact surface of the cable. The cable contact surface is a steel concave curved surface connected to one end of the push rod, and the curved steel plate extends along the axial direction of the curved surface so that the width of the curved surface is greater than the diameter of the push rod. The tail end of the jack is also provided with a base, and a movable jack handle is arranged on the base.

Abstract

A cable curving machine comprises two collar clamps and a jacking device, and the jacking device is arranged between the two collar clamps. The jacking device comprises an ejector bar, wherein a cable contact face corresponding to the shape of a cable is arranged at the top end of the ejector bar, and a force applying device is connected to the tail end of the ejector bar. By applying the cable curving machine, cables in different environments and laying modes can meet requirements and has good effect.

Description

technical field [0001] The invention belongs to the field of electric power technology, in particular to a special cable bending machine suitable for laying 220kV large cross-section power cables in horizontal snaking or vertical wave laying. Background technique [0002] Due to the continuous progress of electric power development, more and more ultra-high-voltage large-section power cables are used in power transmission equipment today. Changes, the influence of irregular vibration of electrodynamic force, etc. According to scientific research experiments, laying cables in horizontal snakes or vertical waves will reduce or eliminate the above-mentioned problems. Short and the pressure of the hydraulic point is too large, the pressure point is too concentrated, and the cable is damaged, and the pressure is too small to meet the needs of the arc length or radian. Contents of the invention [0003] The technical problem to be solved by the present invention: when 220kV lar...
